Unspecified juvenile rheumatoid arthritis, left knee

This code signifies a diagnosis of juvenile rheumatoid arthritis (JRA) affecting the left knee, where the specific type of JRA (e.g., oligoarticular, polyarticular, systemic) has not been documented by the provider. It indicates chronic inflammatory arthritis with onset before 16 years of age, presenting with symptoms localized to the left knee joint.

Use this code when the medical record clearly states JRA involving the left knee, but lacks further specification regarding the subtype of JRA. This is appropriate when the physician's documentation only identifies "juvenile rheumatoid arthritis of the left knee" without additional clinical details to classify it further.

• Always seek clarification from the provider if the specific type of JRA is not documented, as more specific codes exist.
• Do not use this code if the documentation specifies a particular subtype of JRA (e.g., M08.061 for right knee, M08.069 for unspecified knee).
• Ensure laterality (left knee) is clearly documented to support the use of this specific code.
